2、l filler pipe material system defined by this specification requires corrosion protection and resistance to Ford Test Fuels. The pipe construction is typically a low carbon electroplated sheet steel, formed and welded into tubing, with an organic immersion top coat which may form a duplex system. St

3、ainless steel could also be used and may not require coating. Approved suppliers are on the Approved Source List. 2. APPLICATION This specification was released originally for materials used for chassis mounted fuel filler pipes that may or may not be seen with wheels on ground and do not experience

4、 continuous operating temperatures above 121 C (250 F). This specification is not intended to limit the substrate or coating to any specific material type or process, but define the performance of the system. This specification is intended for global use, unless noted on the Approved Source List. Th

5、e coatings and materials approved to this specification may have fuel type restrictions. 2.1 LIMITATIONS FOR FUEL COMPATIBILITY ONLY Note: All approved suppliers may not be approved for all of the Ford Test Fuels for liquid phase and vapor phase. See Product Engineerings Strategy/Design Rule for the

11、 be noted on the Engineering Drawing. Part racking exceptions must be shown on the Engineering Drawing. 3.3.4 Coating Thickness, m As specified on (FLTM BI 117-01, ASTM B 487) engineering drawing Any suitable method may be used to measure coating thickness. Metallurgical cross-section is the final d

12、eterminant. A minimum of twelve measurements are to be taken per pipe: three in the funnel/bowl area, three in the midsection, three near the end of the pipe and three in the inside of the funnel bowl, unless otherwise specified on the Engineering Drawing. Each individual measurement must meet the m

13、inimum thickness, as specified on the Engineering Drawing. The minimum thickness will be established based on original test samples for the Corrosion and Fuel Compatibility Testing. 3.4 RESISTANCE PROPERTIES 3.4.1 Fuel Resistance (Coated and uncoated pipe) No softening or peeling (Fuels per FLTM AZ

The amount of allowable discoloration or oxide formation can vary depending on fuel and pipe material. Requirement: Pass/Fail decision for fuel resistance must

15、 be determined by Materials Engineering and Core Fuel Product Engineering via the attached sign off form (Appendix 1). Reference FLTM BZ 105-03 for evaluation criteria. Additionally, coated pipes shall exhibit no permanent softening of coating after 24h drying at 23 +/-2 C and 50% relative humidity.

16、 Data and signoff will be stored in the Materials Engineering share drive. The pipe must be requalified every 5 years. If a new fuel is added to FLTM AZ 105-02, the part must be retested to the new fuel. 3.4.2 Laboratory Accelerated Cyclic Corrosion Test (Coated and uncoated pipes) (CETP 00.00-L-467

17、 for 12 weeks, X-scribe and Gravelometer ) Note: Precondition one side of the pipe using an X-scribe (Figure 1) with a carbide tip tool, per ASTM D 3359, and stone chip (Figure 2) one location on the other side of the pipe, per SAE J400 (Figures 3 and 4), 1 pint at room temperature.

GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requirem

26、ents of this specification. 4.1 PRETREATMENT (COATED PIPE ONLY) A pretreatment may be used to increase the adhesion and durability of the organic top coating by providing a clean, grease free, corrosion inhibiting bond between the base material and finish. The specification of the pretreatment syste

27、m (including cleaning requirements, pretreatment type and coating weight) is to be determined on initial qualification of materials and process. A control plan with detailed material description and process parameters is required for approval submission. Once the system is approved, any further chan

28、ges will need to be re-submitted to the appropriate Ford Materials Engineer for evaluation and approval. Coating weights should be measured on samples prior to immersion coating and should be tested using x-ray spectroscopy, atomic absorption or inductive coupled plasma testing apparatus. A chromium

29、-free pretreatment is preferable, but at a minimum the pretreatment shall be free of hexavalent chromium. 4.2 RECOMMENDED TESTING FOR COATING CHANGES For coating process changes, see Table 1 for test requirement guidelines.
